1 Introduction
The energy resource distribution and energy consumptionpattern in China are inconsistentThe regions with abundantenergy resources are usually far from the economy-developedregionswith large energy consumption [1] Facing the currentsituations such as the coal-dominated energy structurereverse distribution between energy production and con-sumption and the rapid development of renewable energyindustry China needs to build the strong power grid to realizethe optimal configuration of different energy resources inlarger area and then the electricity demands of the socialeconomic development as well as peoplersquos livelihood can bemet The current 500 kV power grid in China is limitedfor the long-distance and large-volume electricity powertransmission and it is difficult to efficiently transmit theelectricity power generated by the western hydropower baseand the north coal-power base to the central and easternregions of China Therefore to advance the harmoniousdevelopment of both the economy and society building theultra high voltage (UHV)power transmission systemwith the
transmission capacity of long distance high capacity and lowloss is of great importance which can promote the intensi-fication development of large-scale coal-power hydropowerand nuclear-power generation bases optimize the energyproduction and consumption pattern and enhance the safetyand reliability of Chinarsquos power grid [2]
In China the UHV power transmission constructionprojects are dispersed in many areas which will face manyissues such as harsh natural environment many participa-tion partners a lot of works high above the ground andcomplicated local relationshipTheUHVpower transmissionconstruction project is the combination of technologicalinnovation and engineering construction which has thecharacteristics of high technological requirement heavyworkload and significant demonstration effect Comparedwith the conventional construction projects the UHV powertransmission construction project faces more challenges andrisks Therefore building the risk evaluation index systemand evaluating the comprehensive risk of UHV power trans-mission construction project are quite necessary To thebest of our knowledge many researchers who study the

power project issues put their attentions on power generationprojects [3ndash7] and some researchers evaluate the risk ofultra-deep scientific drilling project [8] undergroundminingproject [9] PPP waste-to-energy incineration projects [10]intelligent software project [11] and so on However it is veryregretful to find that the risk of UHV power transmissionconstruction project has rarely been studied The risk eval-uation on UHV power transmission construction project canidentify the risk of project and provide some suggestions forthe risk management and control
ldquoZhejiang-Fuzhourdquo UHV power transmission construc-tion project is a key power grid project invested by theState Grid Corporation of China (SGCC) which plays animportant role in keeping the power network operating insafe and stable condition promoting the efficient utilizationof Chinarsquos energy and advancing the regional economicdevelopment The risk of ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project was evaluated by usinganalytic hierarchy process (AHP) and fuzzy comprehensiveevaluation (FCE) method in this paper (the reason whyweselected AHP and FCE method to perform the riskevaluation will be discussed in Section 4) The evaluationresult can identify the risk level of this project point out thekey risk criteria that need to be paid more attention andprovide the basis for the recommendations of controlling theproject risk
The paper is organized as follows Section 2 provides anoverview of ldquoZhejiang-Fuzhourdquo UHV power transmissionconstruction project which lays the foundation for buildingthe risk evaluation index system Section 3 identifies therisk index of ldquoZhejiang-Fuzhourdquo UHV power transmissionconstruction project by using Delphi method and buildsthe risk evaluation index system The risk evaluation ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject based on AHP and FCE method is performed inSection 4 Specific risk control recommendations are pro-posed in Section 5 Section 6 concludes this paper
2 Overview of lsquolsquoZhejiang-Fuzhoursquorsquo UHVPower Transmission Construction Project
21 Project Profile ldquoZhejiang-Fuzhourdquo UHV power trans-mission construction project is invested by the SGCC whichconnects the 1000 kV substation located in the north ofZhejiang province and 1000 kV substation located in Fuzhoucity (the provincial capital of Fujian) just as shown inFigure 1 This project will build three new UHV transformersubstations and two 603 km-length AC transmission linesThe static and dynamic investments of this project amountto 20716 and 21336 billion Yuan respectively The capitalrequired in this project is composed of own fund and bankloan which accounts for 20 and 80 respectively As thelegal representative the SGCC is responsible for this projectrsquosconstruction operation and repayment of loan principal andinterest ldquoZhejiang-Fuzhourdquo UHV power transmission con-struction project is very urgent in terms of project durationwhich plans to be put into operation during the ldquo12th Five-Year Planrdquo period If this project can be constructed and put

Figure 1 Geographical distribution of ldquoZhejiang-Fuzhourdquo UHVpower transmission construction project
into operation as planned the power transmission bottleneckof East China Power System can be mitigated and the safeand reliable operation of East China Power System can alsobe enhanced Meanwhile this project will make preparationfor the future construction of UHV power grid
This project is an important part of building the strongpower grid of East China Power System and it is alsoan ACDC UHV power receiving platform for Zhejiangand Fujian power grid This project plays a crucial role insupporting the safe and stable operation of power grid withUHVDC accessing the Zhejiang power grid Meanwhile itprovides a main power exchange channel from Zhejiang toFujian More importantly this construction project could fillthe electricity gap of Zhejiang power grid and send out thepower surplus of Fujian power grid during the ldquo12th Five-YearPlanrdquo period
22 Project Characteristics ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project has many special charac-teristics just as follows
221 Tight Time According to the milestone plan the UHVtransformer substation project was commenced at the end of2012 while the transmission line excavation was started inMarch 2013 and planned to be completed in December 2014Due to the delaying of approval from the National EnergyAdministration and the relevant preresearching reports it isimpossible to reach the target of being approved at the end ofthis year which will affect the subsequent project tasks suchas construction drawing design project bidding and contractsigning If the operation schedule remains unchanged theeffective project duration will be significantly shortened

222 Heavy Task For this project the land acquisitionformality is very complicated with heavy workload and longprocess At some substation sites some farms and graves needto be relocated Meanwhile when the project workers carriedout drilling and performed land acquisition some villagersobstructed them by using the negative effect of electromag-netic radiation as an excuse Moreover the transmission linewould pass through the areas with widely distributedmineralresources and numerous nature reserves which will bring anegative impact on the project construction The local folkcustom is another big concern What is more the majorequipment and materials for substationsrsquo and transmissionlinesrsquo constructions need take long time and huge workloadto manufacture which is quite likely to go beyond theproduction capacity of domestic equipment manufacturingenterprises
223 Difficult Construction The construction of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project willface many difficulties The substation project will encounterlarge earthwork cutting-filling and massive piling construc-tionsThe installed equipment is miscellaneous and both theinstallation and testing standards are strict The equipmenttransportation is difficult and many roads and bridges needto be broadened and reinforced The geological feature andfoundation type along the project line are quite complex andthe required construction technique level is highThe terrainalong the project line is undulate with high altitude so it isdifficult to transport the tower construction materials Theproject line crosses a large number of roads and rivers whichmakes the construction more complicated
224 Complicated Environment There are many tasksof ldquoZhejiang-Fuzhourdquo UHV power transmission projectincluding project approval feasibility study design start andcompleted acceptance and so on All these tasks face differentexternal environments Meanwhile with the market openingand economic development in China the numbers of policiesand laws affecting the project construction are increasingIn China the society is relatively stable and harmoniousbut it is undeniable that there are still some problems andcontradictions in some social areas some of which are veryserious that may adversely affect and even hinder this projectconstruction if not handled properly What is more thisproject locates along the southeast coast where the geologicalconditions are quite complex with a lot of mountains andhills
3 Building the Risk Evaluation Index System
Risk index identification is a basis for building the risk eval-uation index system which is the beginning of UHV powertransmission construction project management The goal ofrisk index identification is to identify themost important riskindex Commonly the risk index could be identified by usingDelphimethodwhich relies on the perceptual knowledge andexperience of a panel of experts
Analyze the project characteristics and collect the relevant literatures and
documents
Select the experts in the field of power grid construction and project managers
Design and distribute the questionnaire
Calculate and classify the questionnaire results
Do all the experts hold the same opinion
No
Yes
Obtain the risk factors and build the risk evaluation index system
Figure 2 The procedure of risk index identification
For ldquoZhejiang-Fuzhourdquo UHV power transmission con-struction project based on the project characteristics as wellas the relevant literatures and documents the risk index ofUHV power transmission construction project is identifiedby using Delphi method The risk index identification proce-dure is shown in Figure 2
The questionnaire regarding the risk of ldquoZhejiang-Fuzhourdquo UHV power transmission construction projectincludesmore than 60 risk indicatorsThe experts and projectmanagers conducted the questionnaire survey based on theirknowledge and experience By calculating the questionnaireresults 39 main risk indicators are selected for the ldquoZhejiang-Fuzhourdquo UHV power transmission construction projectwhich are called the second-level risk index According to
4 Mathematical Problems in Engineering
the characteristics of selected risk indicators and the expertadvices these 39 risk indicators are divided into ldquopolicyand law riskrdquo ldquomanagement riskrdquo ldquotechnology riskrdquo ldquonaturalenvironment riskrdquo and ldquosociety riskrdquo which are called thefirst-level risk criteria Therefore the risk evaluation indexsystem of ldquoZhejiang-Fuzhourdquo UHV power transmission con-struction project is built just as shown in Figure 3 FromFigure 3 we can see that the risk evaluation index systemcontains 5 first-level risk criteria and 39 second-level riskindicators
4 Risk Evaluation on lsquolsquoZhejiang-FuzhoursquorsquoUHV Power Transmission ConstructionProject Based on AHP and FCM
Therisk evaluation on ldquoZhejiang-FuzhourdquoUHVpower trans-mission construction project targets the safe and smoothoperation of project Risk evaluation is the combinationof qualitative evaluation and quantitative evaluation Withregard to the UHV power transmission construction projectit is very hard to describe some risk factors with quantitativemethods precisely moreover some risk factors are valuedby experts with certain ambiguity Therefore the risk ofUHV power transmission construction project needs to beevaluated by using a certain fuzzy evaluationmethod In viewof this characteristic the fuzzy comprehensive evaluation(FCE) method is employed in this paper
Determining the weight of each risk indicator is a difficultbut crucial work when using FCEmethod to evaluate the riskof UHV power transmission construction project Whetherthe index weight value is reasonable or not is directly relatedto the reliability of risk evaluation result With regard tothe risk evaluation of UHV power transmission constructionproject it is a multiobjective issue that needs to considermany uncertain factors such as policy society and envi-ronment and so on meanwhile it also has a hierarchicalstructure Therefore the AHP method which can effectivelydeal with the issue with a hierarchical structure and considerthe wisdom and experience of expert to overcome theuncertain factors is selected to determine the risk indexweight
The AHP is a multiobjective decision-making tool com-bining qualitative and quantitative analysis [12] Its principleis as follows firstly divide the research issue into a hierarchi-cal structure based on the interrelationship and membershipbetween indicators secondly compare the importance ofeach indicator within the same layer with regard to theupper layer depending on the experience or intuition ofexperts thirdly obtain the importance of each indicatorwith regard to the final object through the hierarchicalstructure and use the consistency test to justify the resultaccuracy [13 14] The risk evaluation index system of UHVpower transmission construction project is such a systemthat contains a multilevel hierarchical structure and existscorrelation among indicators Therefore it is suitable to useAHP method to determine the weights of risk indicators
FCE method intended to quantify the vague factorswhich are difficult to quantify based on fuzzy mathematical
Table 1 The meaning of different risk types
Risk types Meaning
High risk The occurrence probability of project risk is greatand the risk occurrence will cause huge loss
Moderate riskThe occurrence probability of project risk ismedium and the risk occurrence will causegeneral loss
Low risk The occurrence probability of project risk is lowand the risk occurrence will cause small loss
method is a fuzzy bottom-up multicriteria decision making(MCDM) method [15 16] As a specific application of fuzzymathematics method FCE method was proposed by theChinese scholar P Z Wang Considering the various factorsassociated with the evaluation system the FCE method usesthe fuzzy linear transformation principle and maximummembership degree principle to quantify the fuzzy indicators
The framework of risk evaluation on ldquoZhejiang-FuzhourdquoUHV power transmission construction project based onAHP and FCMmethod is shown in Figure 4
The specific calculation steps for the risk evaluation onldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject based on AHP and FCE method are as follows
41 Step 1 Building the Risk Evaluation Index System Theriskevaluation index system of ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project has been built in Section 3just as shown in Figure 3
42 Step 2 Determine the Evaluated Object and EvaluationIndex Set For the evaluated object F the evaluation index set119862 = 119862
119894 (119894 = 1 2 119899) is an entiretywith intrinsic structure
composing of the indicators that represent the characteristicsof the evaluated object F
In this paper the evaluated object F is the risk ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject The evaluation index set is composed of 39 riskindicators namely 119862 = 119862
119894 (119894 = 1 2 39)
43 Step 3 Give the Remark Set According to the evaluationstandard and grade the remark set V = [V
1 V2 V
119898] can
be made based on the opinions of experts and engineersconsidering the qualitative index and quantitative indextogether The remark set V is composed of different riskgrades and 119898 in the remark set V represents the number ofrisk grades
In this paper according to the characteristics ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject and the expertise suggestion in the field of powergrid construction project the evaluated risk is divided intothree types namely ldquohigh riskrdquo ldquomoderate riskrdquo and ldquolowriskrdquo the meanings of which are listed in Table 1 Thus theremark set V can be made namely V = [V

444 Substep 4 Consistency Test The consistency of relativeimportance judgment on each indicator made by expertsand engineers is the key prerequisite for using the AHP todetermine the weights of risk indicators Hence it is verynecessary to test the consistency of judgment matrix Whenthe consistency of judgmentmatrix is satisfied themaximumeigenvalue of the judgmentmatrix120582max should be equal to thenumber of indicators which are related to two consistencytest indices namely CI and CR
Consistency index (CI) which measures the divergenceof judgment matrix away from the consistency is defined asfollows
CI =120582max minus 119899
119899 minus 1 (1)
where 119899 represents the number of indicesThus the consistency ratio (CR) is defined as follows
CR =CIRI
(2)
RI is the random consistency index which is the averagevalue of eigenvalues obtained by calculating the judgmentmatrix for more than 500 times The value of RI is given inTable 9
If CR lt 01 the weight vector is acceptable otherwisethe modification of the pairwise judgment matrix is needed
As listed in the last row in Tables 3ndash8 respectivelyall the pairwise comparison judgment matrixes satisfy theconsistency test
445 Substep 5 Calculate the Index Weight The globalweight of each indicator can be determined by multiplying
the local weight of the indicator with theweight of upper layerindicator which locates in the parent node above it
The local and global weights of each risk indicator inindex layer and the weight of each indicator in criteria layerare calculated which are listed in Table 10
45 Step 5 Calculate the Fuzzy Relation Matrix Accordingto the statistical result of the questionnaire by using a certainmathematical method such as frequency-based method andweighted averagemethod the first-level fuzzy relationmatrixR can be calculated as follows
R = (119903119894119895)119899times119898

where 119903119894119895is the membership degree of the 119895th remark in

The frequency-based method is used to establish thefuzzy relation matrix in this paper the principle of which isif the number of experts and engineers who judge the ldquohighriskrdquo ldquomoderate riskrdquo and ldquolow riskrdquo is119898

1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object

carry out some specific risk control measures to make theconstruction of this project run successfully
At the meantime valuing the evaluation result of indi-cators in criteria layer in centesimal form can help projectmanagers to analyze the project riskmore efficiently Supposethe comment set V = [V
1 V2 V3] = 90 50 10 and then
the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10
= 362830
1198803= 01073 times 90 + 05905 times 50 + 03022 times 10
= 422
1198804= 01128 times 90 + 04736 times 50 + 04136 times 10
= 379660
1198805= 01710 times 90 + 05133 times 50 + 03157 times 10
= 442085
(12)
The centesimal value (119880) of risk evaluation of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project canbe calculated as
119880 = 01385 times 90 + 04990 times 50 + 03603 times 10
= 410205

(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway

power project issues put their attentions on power generationprojects [3ndash7] and some researchers evaluate the risk ofultra-deep scientific drilling project [8] undergroundminingproject [9] PPP waste-to-energy incineration projects [10]intelligent software project [11] and so on However it is veryregretful to find that the risk of UHV power transmissionconstruction project has rarely been studied The risk eval-uation on UHV power transmission construction project canidentify the risk of project and provide some suggestions forthe risk management and control
ldquoZhejiang-Fuzhourdquo UHV power transmission construc-tion project is a key power grid project invested by theState Grid Corporation of China (SGCC) which plays animportant role in keeping the power network operating insafe and stable condition promoting the efficient utilizationof Chinarsquos energy and advancing the regional economicdevelopment The risk of ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project was evaluated by usinganalytic hierarchy process (AHP) and fuzzy comprehensiveevaluation (FCE) method in this paper (the reason whyweselected AHP and FCE method to perform the riskevaluation will be discussed in Section 4) The evaluationresult can identify the risk level of this project point out thekey risk criteria that need to be paid more attention andprovide the basis for the recommendations of controlling theproject risk
The paper is organized as follows Section 2 provides anoverview of ldquoZhejiang-Fuzhourdquo UHV power transmissionconstruction project which lays the foundation for buildingthe risk evaluation index system Section 3 identifies therisk index of ldquoZhejiang-Fuzhourdquo UHV power transmissionconstruction project by using Delphi method and buildsthe risk evaluation index system The risk evaluation ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject based on AHP and FCE method is performed inSection 4 Specific risk control recommendations are pro-posed in Section 5 Section 6 concludes this paper
2 Overview of lsquolsquoZhejiang-Fuzhoursquorsquo UHVPower Transmission Construction Project
21 Project Profile ldquoZhejiang-Fuzhourdquo UHV power trans-mission construction project is invested by the SGCC whichconnects the 1000 kV substation located in the north ofZhejiang province and 1000 kV substation located in Fuzhoucity (the provincial capital of Fujian) just as shown inFigure 1 This project will build three new UHV transformersubstations and two 603 km-length AC transmission linesThe static and dynamic investments of this project amountto 20716 and 21336 billion Yuan respectively The capitalrequired in this project is composed of own fund and bankloan which accounts for 20 and 80 respectively As thelegal representative the SGCC is responsible for this projectrsquosconstruction operation and repayment of loan principal andinterest ldquoZhejiang-Fuzhourdquo UHV power transmission con-struction project is very urgent in terms of project durationwhich plans to be put into operation during the ldquo12th Five-Year Planrdquo period If this project can be constructed and put

1000 kV
Figure 1 Geographical distribution of ldquoZhejiang-Fuzhourdquo UHVpower transmission construction project
into operation as planned the power transmission bottleneckof East China Power System can be mitigated and the safeand reliable operation of East China Power System can alsobe enhanced Meanwhile this project will make preparationfor the future construction of UHV power grid
This project is an important part of building the strongpower grid of East China Power System and it is alsoan ACDC UHV power receiving platform for Zhejiangand Fujian power grid This project plays a crucial role insupporting the safe and stable operation of power grid withUHVDC accessing the Zhejiang power grid Meanwhile itprovides a main power exchange channel from Zhejiang toFujian More importantly this construction project could fillthe electricity gap of Zhejiang power grid and send out thepower surplus of Fujian power grid during the ldquo12th Five-YearPlanrdquo period
22 Project Characteristics ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project has many special charac-teristics just as follows
221 Tight Time According to the milestone plan the UHVtransformer substation project was commenced at the end of2012 while the transmission line excavation was started inMarch 2013 and planned to be completed in December 2014Due to the delaying of approval from the National EnergyAdministration and the relevant preresearching reports it isimpossible to reach the target of being approved at the end ofthis year which will affect the subsequent project tasks suchas construction drawing design project bidding and contractsigning If the operation schedule remains unchanged theeffective project duration will be significantly shortened
Mathematical Problems in Engineering 3
222 Heavy Task For this project the land acquisitionformality is very complicated with heavy workload and longprocess At some substation sites some farms and graves needto be relocated Meanwhile when the project workers carriedout drilling and performed land acquisition some villagersobstructed them by using the negative effect of electromag-netic radiation as an excuse Moreover the transmission linewould pass through the areas with widely distributedmineralresources and numerous nature reserves which will bring anegative impact on the project construction The local folkcustom is another big concern What is more the majorequipment and materials for substationsrsquo and transmissionlinesrsquo constructions need take long time and huge workloadto manufacture which is quite likely to go beyond theproduction capacity of domestic equipment manufacturingenterprises
223 Difficult Construction The construction of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project willface many difficulties The substation project will encounterlarge earthwork cutting-filling and massive piling construc-tionsThe installed equipment is miscellaneous and both theinstallation and testing standards are strict The equipmenttransportation is difficult and many roads and bridges needto be broadened and reinforced The geological feature andfoundation type along the project line are quite complex andthe required construction technique level is highThe terrainalong the project line is undulate with high altitude so it isdifficult to transport the tower construction materials Theproject line crosses a large number of roads and rivers whichmakes the construction more complicated
224 Complicated Environment There are many tasksof ldquoZhejiang-Fuzhourdquo UHV power transmission projectincluding project approval feasibility study design start andcompleted acceptance and so on All these tasks face differentexternal environments Meanwhile with the market openingand economic development in China the numbers of policiesand laws affecting the project construction are increasingIn China the society is relatively stable and harmoniousbut it is undeniable that there are still some problems andcontradictions in some social areas some of which are veryserious that may adversely affect and even hinder this projectconstruction if not handled properly What is more thisproject locates along the southeast coast where the geologicalconditions are quite complex with a lot of mountains andhills
3 Building the Risk Evaluation Index System
Risk index identification is a basis for building the risk eval-uation index system which is the beginning of UHV powertransmission construction project management The goal ofrisk index identification is to identify themost important riskindex Commonly the risk index could be identified by usingDelphimethodwhich relies on the perceptual knowledge andexperience of a panel of experts
Analyze the project characteristics and collect the relevant literatures and
documents
Select the experts in the field of power grid construction and project managers
Design and distribute the questionnaire
Calculate and classify the questionnaire results
Do all the experts hold the same opinion
No
Yes
Obtain the risk factors and build the risk evaluation index system
Figure 2 The procedure of risk index identification
For ldquoZhejiang-Fuzhourdquo UHV power transmission con-struction project based on the project characteristics as wellas the relevant literatures and documents the risk index ofUHV power transmission construction project is identifiedby using Delphi method The risk index identification proce-dure is shown in Figure 2
The questionnaire regarding the risk of ldquoZhejiang-Fuzhourdquo UHV power transmission construction projectincludesmore than 60 risk indicatorsThe experts and projectmanagers conducted the questionnaire survey based on theirknowledge and experience By calculating the questionnaireresults 39 main risk indicators are selected for the ldquoZhejiang-Fuzhourdquo UHV power transmission construction projectwhich are called the second-level risk index According to
4 Mathematical Problems in Engineering
the characteristics of selected risk indicators and the expertadvices these 39 risk indicators are divided into ldquopolicyand law riskrdquo ldquomanagement riskrdquo ldquotechnology riskrdquo ldquonaturalenvironment riskrdquo and ldquosociety riskrdquo which are called thefirst-level risk criteria Therefore the risk evaluation indexsystem of ldquoZhejiang-Fuzhourdquo UHV power transmission con-struction project is built just as shown in Figure 3 FromFigure 3 we can see that the risk evaluation index systemcontains 5 first-level risk criteria and 39 second-level riskindicators
4 Risk Evaluation on lsquolsquoZhejiang-FuzhoursquorsquoUHV Power Transmission ConstructionProject Based on AHP and FCM
Therisk evaluation on ldquoZhejiang-FuzhourdquoUHVpower trans-mission construction project targets the safe and smoothoperation of project Risk evaluation is the combinationof qualitative evaluation and quantitative evaluation Withregard to the UHV power transmission construction projectit is very hard to describe some risk factors with quantitativemethods precisely moreover some risk factors are valuedby experts with certain ambiguity Therefore the risk ofUHV power transmission construction project needs to beevaluated by using a certain fuzzy evaluationmethod In viewof this characteristic the fuzzy comprehensive evaluation(FCE) method is employed in this paper
Determining the weight of each risk indicator is a difficultbut crucial work when using FCEmethod to evaluate the riskof UHV power transmission construction project Whetherthe index weight value is reasonable or not is directly relatedto the reliability of risk evaluation result With regard tothe risk evaluation of UHV power transmission constructionproject it is a multiobjective issue that needs to considermany uncertain factors such as policy society and envi-ronment and so on meanwhile it also has a hierarchicalstructure Therefore the AHP method which can effectivelydeal with the issue with a hierarchical structure and considerthe wisdom and experience of expert to overcome theuncertain factors is selected to determine the risk indexweight
The AHP is a multiobjective decision-making tool com-bining qualitative and quantitative analysis [12] Its principleis as follows firstly divide the research issue into a hierarchi-cal structure based on the interrelationship and membershipbetween indicators secondly compare the importance ofeach indicator within the same layer with regard to theupper layer depending on the experience or intuition ofexperts thirdly obtain the importance of each indicatorwith regard to the final object through the hierarchicalstructure and use the consistency test to justify the resultaccuracy [13 14] The risk evaluation index system of UHVpower transmission construction project is such a systemthat contains a multilevel hierarchical structure and existscorrelation among indicators Therefore it is suitable to useAHP method to determine the weights of risk indicators
FCE method intended to quantify the vague factorswhich are difficult to quantify based on fuzzy mathematical
Table 1 The meaning of different risk types
Risk types Meaning
High risk The occurrence probability of project risk is greatand the risk occurrence will cause huge loss
Moderate riskThe occurrence probability of project risk ismedium and the risk occurrence will causegeneral loss
Low risk The occurrence probability of project risk is lowand the risk occurrence will cause small loss
method is a fuzzy bottom-up multicriteria decision making(MCDM) method [15 16] As a specific application of fuzzymathematics method FCE method was proposed by theChinese scholar P Z Wang Considering the various factorsassociated with the evaluation system the FCE method usesthe fuzzy linear transformation principle and maximummembership degree principle to quantify the fuzzy indicators
The framework of risk evaluation on ldquoZhejiang-FuzhourdquoUHV power transmission construction project based onAHP and FCMmethod is shown in Figure 4
The specific calculation steps for the risk evaluation onldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject based on AHP and FCE method are as follows
41 Step 1 Building the Risk Evaluation Index System Theriskevaluation index system of ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project has been built in Section 3just as shown in Figure 3
42 Step 2 Determine the Evaluated Object and EvaluationIndex Set For the evaluated object F the evaluation index set119862 = 119862
119894 (119894 = 1 2 119899) is an entiretywith intrinsic structure
composing of the indicators that represent the characteristicsof the evaluated object F
In this paper the evaluated object F is the risk ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject The evaluation index set is composed of 39 riskindicators namely 119862 = 119862
119894 (119894 = 1 2 39)
43 Step 3 Give the Remark Set According to the evaluationstandard and grade the remark set V = [V
1 V2 V
119898] can
be made based on the opinions of experts and engineersconsidering the qualitative index and quantitative indextogether The remark set V is composed of different riskgrades and 119898 in the remark set V represents the number ofrisk grades
In this paper according to the characteristics ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject and the expertise suggestion in the field of powergrid construction project the evaluated risk is divided intothree types namely ldquohigh riskrdquo ldquomoderate riskrdquo and ldquolowriskrdquo the meanings of which are listed in Table 1 Thus theremark set V can be made namely V = [V

444 Substep 4 Consistency Test The consistency of relativeimportance judgment on each indicator made by expertsand engineers is the key prerequisite for using the AHP todetermine the weights of risk indicators Hence it is verynecessary to test the consistency of judgment matrix Whenthe consistency of judgmentmatrix is satisfied themaximumeigenvalue of the judgmentmatrix120582max should be equal to thenumber of indicators which are related to two consistencytest indices namely CI and CR
Consistency index (CI) which measures the divergenceof judgment matrix away from the consistency is defined asfollows
CI =120582max minus 119899
119899 minus 1 (1)
where 119899 represents the number of indicesThus the consistency ratio (CR) is defined as follows
CR =CIRI
(2)
RI is the random consistency index which is the averagevalue of eigenvalues obtained by calculating the judgmentmatrix for more than 500 times The value of RI is given inTable 9
If CR lt 01 the weight vector is acceptable otherwisethe modification of the pairwise judgment matrix is needed
As listed in the last row in Tables 3ndash8 respectivelyall the pairwise comparison judgment matrixes satisfy theconsistency test
445 Substep 5 Calculate the Index Weight The globalweight of each indicator can be determined by multiplying
the local weight of the indicator with theweight of upper layerindicator which locates in the parent node above it
The local and global weights of each risk indicator inindex layer and the weight of each indicator in criteria layerare calculated which are listed in Table 10
45 Step 5 Calculate the Fuzzy Relation Matrix Accordingto the statistical result of the questionnaire by using a certainmathematical method such as frequency-based method andweighted averagemethod the first-level fuzzy relationmatrixR can be calculated as follows
R = (119903119894119895)119899times119898

where 119903119894119895is the membership degree of the 119895th remark in
remark set V for the indicator 119894 119894 = 1 2 119899 119895 =
1 2 119898 119899 is the number of indices and 119898 is the numberof risk grades in remark set V Different rows in the fuzzyrelation matrix R reflect the different membership degrees ofevaluated object subject to fuzzy set of each grade consideringdifferent evaluation indices
The frequency-based method is used to establish thefuzzy relation matrix in this paper the principle of which isif the number of experts and engineers who judge the ldquohighriskrdquo ldquomoderate riskrdquo and ldquolow riskrdquo is119898

Then combined with the weight matrix 119882 the second-level fuzzy comprehensive evaluation matrix B can be calcu-lated as follows

1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object
belongs to the 1198940grade
In this paper since 1198872

04990 it is shown that the risk grade of ldquoZhejiang-FuzhourdquoUHV power transmission construction project belongs toldquomoderaterdquo which means the occurrence probability of thisproject risk is medium and the risk occurrence will causegeneral loss So it is necessary for the project managers to

carry out some specific risk control measures to make theconstruction of this project run successfully
At the meantime valuing the evaluation result of indi-cators in criteria layer in centesimal form can help projectmanagers to analyze the project riskmore efficiently Supposethe comment set V = [V
1 V2 V3] = 90 50 10 and then
the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10
= 362830
1198803= 01073 times 90 + 05905 times 50 + 03022 times 10
= 422
1198804= 01128 times 90 + 04736 times 50 + 04136 times 10
= 379660
1198805= 01710 times 90 + 05133 times 50 + 03157 times 10
= 442085
(12)
The centesimal value (119880) of risk evaluation of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project canbe calculated as
119880 = 01385 times 90 + 04990 times 50 + 03603 times 10
= 410205

(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway

222 Heavy Task For this project the land acquisitionformality is very complicated with heavy workload and longprocess At some substation sites some farms and graves needto be relocated Meanwhile when the project workers carriedout drilling and performed land acquisition some villagersobstructed them by using the negative effect of electromag-netic radiation as an excuse Moreover the transmission linewould pass through the areas with widely distributedmineralresources and numerous nature reserves which will bring anegative impact on the project construction The local folkcustom is another big concern What is more the majorequipment and materials for substationsrsquo and transmissionlinesrsquo constructions need take long time and huge workloadto manufacture which is quite likely to go beyond theproduction capacity of domestic equipment manufacturingenterprises
223 Difficult Construction The construction of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project willface many difficulties The substation project will encounterlarge earthwork cutting-filling and massive piling construc-tionsThe installed equipment is miscellaneous and both theinstallation and testing standards are strict The equipmenttransportation is difficult and many roads and bridges needto be broadened and reinforced The geological feature andfoundation type along the project line are quite complex andthe required construction technique level is highThe terrainalong the project line is undulate with high altitude so it isdifficult to transport the tower construction materials Theproject line crosses a large number of roads and rivers whichmakes the construction more complicated
224 Complicated Environment There are many tasksof ldquoZhejiang-Fuzhourdquo UHV power transmission projectincluding project approval feasibility study design start andcompleted acceptance and so on All these tasks face differentexternal environments Meanwhile with the market openingand economic development in China the numbers of policiesand laws affecting the project construction are increasingIn China the society is relatively stable and harmoniousbut it is undeniable that there are still some problems andcontradictions in some social areas some of which are veryserious that may adversely affect and even hinder this projectconstruction if not handled properly What is more thisproject locates along the southeast coast where the geologicalconditions are quite complex with a lot of mountains andhills
3 Building the Risk Evaluation Index System
Risk index identification is a basis for building the risk eval-uation index system which is the beginning of UHV powertransmission construction project management The goal ofrisk index identification is to identify themost important riskindex Commonly the risk index could be identified by usingDelphimethodwhich relies on the perceptual knowledge andexperience of a panel of experts
Analyze the project characteristics and collect the relevant literatures and
documents
Select the experts in the field of power grid construction and project managers
Design and distribute the questionnaire
Calculate and classify the questionnaire results
Do all the experts hold the same opinion
No
Yes
Obtain the risk factors and build the risk evaluation index system
Figure 2 The procedure of risk index identification
For ldquoZhejiang-Fuzhourdquo UHV power transmission con-struction project based on the project characteristics as wellas the relevant literatures and documents the risk index ofUHV power transmission construction project is identifiedby using Delphi method The risk index identification proce-dure is shown in Figure 2
The questionnaire regarding the risk of ldquoZhejiang-Fuzhourdquo UHV power transmission construction projectincludesmore than 60 risk indicatorsThe experts and projectmanagers conducted the questionnaire survey based on theirknowledge and experience By calculating the questionnaireresults 39 main risk indicators are selected for the ldquoZhejiang-Fuzhourdquo UHV power transmission construction projectwhich are called the second-level risk index According to
4 Mathematical Problems in Engineering
the characteristics of selected risk indicators and the expertadvices these 39 risk indicators are divided into ldquopolicyand law riskrdquo ldquomanagement riskrdquo ldquotechnology riskrdquo ldquonaturalenvironment riskrdquo and ldquosociety riskrdquo which are called thefirst-level risk criteria Therefore the risk evaluation indexsystem of ldquoZhejiang-Fuzhourdquo UHV power transmission con-struction project is built just as shown in Figure 3 FromFigure 3 we can see that the risk evaluation index systemcontains 5 first-level risk criteria and 39 second-level riskindicators
4 Risk Evaluation on lsquolsquoZhejiang-FuzhoursquorsquoUHV Power Transmission ConstructionProject Based on AHP and FCM
Therisk evaluation on ldquoZhejiang-FuzhourdquoUHVpower trans-mission construction project targets the safe and smoothoperation of project Risk evaluation is the combinationof qualitative evaluation and quantitative evaluation Withregard to the UHV power transmission construction projectit is very hard to describe some risk factors with quantitativemethods precisely moreover some risk factors are valuedby experts with certain ambiguity Therefore the risk ofUHV power transmission construction project needs to beevaluated by using a certain fuzzy evaluationmethod In viewof this characteristic the fuzzy comprehensive evaluation(FCE) method is employed in this paper
Determining the weight of each risk indicator is a difficultbut crucial work when using FCEmethod to evaluate the riskof UHV power transmission construction project Whetherthe index weight value is reasonable or not is directly relatedto the reliability of risk evaluation result With regard tothe risk evaluation of UHV power transmission constructionproject it is a multiobjective issue that needs to considermany uncertain factors such as policy society and envi-ronment and so on meanwhile it also has a hierarchicalstructure Therefore the AHP method which can effectivelydeal with the issue with a hierarchical structure and considerthe wisdom and experience of expert to overcome theuncertain factors is selected to determine the risk indexweight
The AHP is a multiobjective decision-making tool com-bining qualitative and quantitative analysis [12] Its principleis as follows firstly divide the research issue into a hierarchi-cal structure based on the interrelationship and membershipbetween indicators secondly compare the importance ofeach indicator within the same layer with regard to theupper layer depending on the experience or intuition ofexperts thirdly obtain the importance of each indicatorwith regard to the final object through the hierarchicalstructure and use the consistency test to justify the resultaccuracy [13 14] The risk evaluation index system of UHVpower transmission construction project is such a systemthat contains a multilevel hierarchical structure and existscorrelation among indicators Therefore it is suitable to useAHP method to determine the weights of risk indicators
FCE method intended to quantify the vague factorswhich are difficult to quantify based on fuzzy mathematical
Table 1 The meaning of different risk types
Risk types Meaning
High risk The occurrence probability of project risk is greatand the risk occurrence will cause huge loss
Moderate riskThe occurrence probability of project risk ismedium and the risk occurrence will causegeneral loss
Low risk The occurrence probability of project risk is lowand the risk occurrence will cause small loss
method is a fuzzy bottom-up multicriteria decision making(MCDM) method [15 16] As a specific application of fuzzymathematics method FCE method was proposed by theChinese scholar P Z Wang Considering the various factorsassociated with the evaluation system the FCE method usesthe fuzzy linear transformation principle and maximummembership degree principle to quantify the fuzzy indicators
The framework of risk evaluation on ldquoZhejiang-FuzhourdquoUHV power transmission construction project based onAHP and FCMmethod is shown in Figure 4
The specific calculation steps for the risk evaluation onldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject based on AHP and FCE method are as follows
41 Step 1 Building the Risk Evaluation Index System Theriskevaluation index system of ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project has been built in Section 3just as shown in Figure 3
42 Step 2 Determine the Evaluated Object and EvaluationIndex Set For the evaluated object F the evaluation index set119862 = 119862
119894 (119894 = 1 2 119899) is an entiretywith intrinsic structure
composing of the indicators that represent the characteristicsof the evaluated object F
In this paper the evaluated object F is the risk ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject The evaluation index set is composed of 39 riskindicators namely 119862 = 119862
119894 (119894 = 1 2 39)
43 Step 3 Give the Remark Set According to the evaluationstandard and grade the remark set V = [V
1 V2 V
119898] can
be made based on the opinions of experts and engineersconsidering the qualitative index and quantitative indextogether The remark set V is composed of different riskgrades and 119898 in the remark set V represents the number ofrisk grades
In this paper according to the characteristics ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject and the expertise suggestion in the field of powergrid construction project the evaluated risk is divided intothree types namely ldquohigh riskrdquo ldquomoderate riskrdquo and ldquolowriskrdquo the meanings of which are listed in Table 1 Thus theremark set V can be made namely V = [V

444 Substep 4 Consistency Test The consistency of relativeimportance judgment on each indicator made by expertsand engineers is the key prerequisite for using the AHP todetermine the weights of risk indicators Hence it is verynecessary to test the consistency of judgment matrix Whenthe consistency of judgmentmatrix is satisfied themaximumeigenvalue of the judgmentmatrix120582max should be equal to thenumber of indicators which are related to two consistencytest indices namely CI and CR
Consistency index (CI) which measures the divergenceof judgment matrix away from the consistency is defined asfollows
CI =120582max minus 119899
119899 minus 1 (1)
where 119899 represents the number of indicesThus the consistency ratio (CR) is defined as follows
CR =CIRI
(2)
RI is the random consistency index which is the averagevalue of eigenvalues obtained by calculating the judgmentmatrix for more than 500 times The value of RI is given inTable 9
If CR lt 01 the weight vector is acceptable otherwisethe modification of the pairwise judgment matrix is needed
As listed in the last row in Tables 3ndash8 respectivelyall the pairwise comparison judgment matrixes satisfy theconsistency test
445 Substep 5 Calculate the Index Weight The globalweight of each indicator can be determined by multiplying
the local weight of the indicator with theweight of upper layerindicator which locates in the parent node above it
The local and global weights of each risk indicator inindex layer and the weight of each indicator in criteria layerare calculated which are listed in Table 10
45 Step 5 Calculate the Fuzzy Relation Matrix Accordingto the statistical result of the questionnaire by using a certainmathematical method such as frequency-based method andweighted averagemethod the first-level fuzzy relationmatrixR can be calculated as follows
R = (119903119894119895)119899times119898

where 119903119894119895is the membership degree of the 119895th remark in
remark set V for the indicator 119894 119894 = 1 2 119899 119895 =
1 2 119898 119899 is the number of indices and 119898 is the numberof risk grades in remark set V Different rows in the fuzzyrelation matrix R reflect the different membership degrees ofevaluated object subject to fuzzy set of each grade consideringdifferent evaluation indices
The frequency-based method is used to establish thefuzzy relation matrix in this paper the principle of which isif the number of experts and engineers who judge the ldquohighriskrdquo ldquomoderate riskrdquo and ldquolow riskrdquo is119898

Then combined with the weight matrix 119882 the second-level fuzzy comprehensive evaluation matrix B can be calcu-lated as follows

47 Step 7 Rate and Conclude the Grade Level Accordingto the maximum membership degree principle when 119887
1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object
belongs to the 1198940grade
In this paper since 1198872

carry out some specific risk control measures to make theconstruction of this project run successfully
At the meantime valuing the evaluation result of indi-cators in criteria layer in centesimal form can help projectmanagers to analyze the project riskmore efficiently Supposethe comment set V = [V
1 V2 V3] = 90 50 10 and then
the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10
= 362830
1198803= 01073 times 90 + 05905 times 50 + 03022 times 10
= 422
1198804= 01128 times 90 + 04736 times 50 + 04136 times 10
= 379660
1198805= 01710 times 90 + 05133 times 50 + 03157 times 10
= 442085
(12)
The centesimal value (119880) of risk evaluation of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project canbe calculated as
119880 = 01385 times 90 + 04990 times 50 + 03603 times 10
= 410205

(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway

the characteristics of selected risk indicators and the expertadvices these 39 risk indicators are divided into ldquopolicyand law riskrdquo ldquomanagement riskrdquo ldquotechnology riskrdquo ldquonaturalenvironment riskrdquo and ldquosociety riskrdquo which are called thefirst-level risk criteria Therefore the risk evaluation indexsystem of ldquoZhejiang-Fuzhourdquo UHV power transmission con-struction project is built just as shown in Figure 3 FromFigure 3 we can see that the risk evaluation index systemcontains 5 first-level risk criteria and 39 second-level riskindicators
4 Risk Evaluation on lsquolsquoZhejiang-FuzhoursquorsquoUHV Power Transmission ConstructionProject Based on AHP and FCM
Therisk evaluation on ldquoZhejiang-FuzhourdquoUHVpower trans-mission construction project targets the safe and smoothoperation of project Risk evaluation is the combinationof qualitative evaluation and quantitative evaluation Withregard to the UHV power transmission construction projectit is very hard to describe some risk factors with quantitativemethods precisely moreover some risk factors are valuedby experts with certain ambiguity Therefore the risk ofUHV power transmission construction project needs to beevaluated by using a certain fuzzy evaluationmethod In viewof this characteristic the fuzzy comprehensive evaluation(FCE) method is employed in this paper
Determining the weight of each risk indicator is a difficultbut crucial work when using FCEmethod to evaluate the riskof UHV power transmission construction project Whetherthe index weight value is reasonable or not is directly relatedto the reliability of risk evaluation result With regard tothe risk evaluation of UHV power transmission constructionproject it is a multiobjective issue that needs to considermany uncertain factors such as policy society and envi-ronment and so on meanwhile it also has a hierarchicalstructure Therefore the AHP method which can effectivelydeal with the issue with a hierarchical structure and considerthe wisdom and experience of expert to overcome theuncertain factors is selected to determine the risk indexweight
The AHP is a multiobjective decision-making tool com-bining qualitative and quantitative analysis [12] Its principleis as follows firstly divide the research issue into a hierarchi-cal structure based on the interrelationship and membershipbetween indicators secondly compare the importance ofeach indicator within the same layer with regard to theupper layer depending on the experience or intuition ofexperts thirdly obtain the importance of each indicatorwith regard to the final object through the hierarchicalstructure and use the consistency test to justify the resultaccuracy [13 14] The risk evaluation index system of UHVpower transmission construction project is such a systemthat contains a multilevel hierarchical structure and existscorrelation among indicators Therefore it is suitable to useAHP method to determine the weights of risk indicators
FCE method intended to quantify the vague factorswhich are difficult to quantify based on fuzzy mathematical
Table 1 The meaning of different risk types
Risk types Meaning
High risk The occurrence probability of project risk is greatand the risk occurrence will cause huge loss
Moderate riskThe occurrence probability of project risk ismedium and the risk occurrence will causegeneral loss
Low risk The occurrence probability of project risk is lowand the risk occurrence will cause small loss
method is a fuzzy bottom-up multicriteria decision making(MCDM) method [15 16] As a specific application of fuzzymathematics method FCE method was proposed by theChinese scholar P Z Wang Considering the various factorsassociated with the evaluation system the FCE method usesthe fuzzy linear transformation principle and maximummembership degree principle to quantify the fuzzy indicators
The framework of risk evaluation on ldquoZhejiang-FuzhourdquoUHV power transmission construction project based onAHP and FCMmethod is shown in Figure 4
The specific calculation steps for the risk evaluation onldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject based on AHP and FCE method are as follows
41 Step 1 Building the Risk Evaluation Index System Theriskevaluation index system of ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project has been built in Section 3just as shown in Figure 3
42 Step 2 Determine the Evaluated Object and EvaluationIndex Set For the evaluated object F the evaluation index set119862 = 119862
119894 (119894 = 1 2 119899) is an entiretywith intrinsic structure
composing of the indicators that represent the characteristicsof the evaluated object F
In this paper the evaluated object F is the risk ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject The evaluation index set is composed of 39 riskindicators namely 119862 = 119862
119894 (119894 = 1 2 39)
43 Step 3 Give the Remark Set According to the evaluationstandard and grade the remark set V = [V
1 V2 V
119898] can
be made based on the opinions of experts and engineersconsidering the qualitative index and quantitative indextogether The remark set V is composed of different riskgrades and 119898 in the remark set V represents the number ofrisk grades
In this paper according to the characteristics ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionproject and the expertise suggestion in the field of powergrid construction project the evaluated risk is divided intothree types namely ldquohigh riskrdquo ldquomoderate riskrdquo and ldquolowriskrdquo the meanings of which are listed in Table 1 Thus theremark set V can be made namely V = [V

444 Substep 4 Consistency Test The consistency of relativeimportance judgment on each indicator made by expertsand engineers is the key prerequisite for using the AHP todetermine the weights of risk indicators Hence it is verynecessary to test the consistency of judgment matrix Whenthe consistency of judgmentmatrix is satisfied themaximumeigenvalue of the judgmentmatrix120582max should be equal to thenumber of indicators which are related to two consistencytest indices namely CI and CR
Consistency index (CI) which measures the divergenceof judgment matrix away from the consistency is defined asfollows
CI =120582max minus 119899
119899 minus 1 (1)
where 119899 represents the number of indicesThus the consistency ratio (CR) is defined as follows
CR =CIRI
(2)
RI is the random consistency index which is the averagevalue of eigenvalues obtained by calculating the judgmentmatrix for more than 500 times The value of RI is given inTable 9
If CR lt 01 the weight vector is acceptable otherwisethe modification of the pairwise judgment matrix is needed
As listed in the last row in Tables 3ndash8 respectivelyall the pairwise comparison judgment matrixes satisfy theconsistency test
445 Substep 5 Calculate the Index Weight The globalweight of each indicator can be determined by multiplying
the local weight of the indicator with theweight of upper layerindicator which locates in the parent node above it
The local and global weights of each risk indicator inindex layer and the weight of each indicator in criteria layerare calculated which are listed in Table 10
45 Step 5 Calculate the Fuzzy Relation Matrix Accordingto the statistical result of the questionnaire by using a certainmathematical method such as frequency-based method andweighted averagemethod the first-level fuzzy relationmatrixR can be calculated as follows
R = (119903119894119895)119899times119898

where 119903119894119895is the membership degree of the 119895th remark in
remark set V for the indicator 119894 119894 = 1 2 119899 119895 =
1 2 119898 119899 is the number of indices and 119898 is the numberof risk grades in remark set V Different rows in the fuzzyrelation matrix R reflect the different membership degrees ofevaluated object subject to fuzzy set of each grade consideringdifferent evaluation indices
The frequency-based method is used to establish thefuzzy relation matrix in this paper the principle of which isif the number of experts and engineers who judge the ldquohighriskrdquo ldquomoderate riskrdquo and ldquolow riskrdquo is119898

46 Step 6 Make Fuzzy Composition Synthesize the first-level fuzzy relation matrix R with the local weight 119882

Then combined with the weight matrix 119882 the second-level fuzzy comprehensive evaluation matrix B can be calcu-lated as follows
B = 119882o1198771015840 = (1198871 1198872 119887

47 Step 7 Rate and Conclude the Grade Level Accordingto the maximum membership degree principle when 119887
1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object
belongs to the 1198940grade
In this paper since 1198872
= max 119887119894(1 le 119894 le 3) =
04990 it is shown that the risk grade of ldquoZhejiang-FuzhourdquoUHV power transmission construction project belongs toldquomoderaterdquo which means the occurrence probability of thisproject risk is medium and the risk occurrence will causegeneral loss So it is necessary for the project managers to

carry out some specific risk control measures to make theconstruction of this project run successfully
At the meantime valuing the evaluation result of indi-cators in criteria layer in centesimal form can help projectmanagers to analyze the project riskmore efficiently Supposethe comment set V = [V
1 V2 V3] = 90 50 10 and then
the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10
= 362830
1198803= 01073 times 90 + 05905 times 50 + 03022 times 10
= 422
1198804= 01128 times 90 + 04736 times 50 + 04136 times 10
= 379660
1198805= 01710 times 90 + 05133 times 50 + 03157 times 10
= 442085
(12)
The centesimal value (119880) of risk evaluation of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project canbe calculated as
119880 = 01385 times 90 + 04990 times 50 + 03603 times 10
= 410205
(13)

(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway

method The eigenvector of judgment matrix with the max-imum eigenvalue is the weight vector of risk index whichdenotes the relative importance of indicators in the same levelwith regard to the indicators in the upper layer The weightvector of risk index is the relative importance of indicators
with regard to the upper layer indicator which is also calledthe local weight
In this paper the weights of indictors in criteria layer andlocal weights of indicators in index layer are calculated whichare lists in Tables 3ndash8 respectively

444 Substep 4 Consistency Test The consistency of relativeimportance judgment on each indicator made by expertsand engineers is the key prerequisite for using the AHP todetermine the weights of risk indicators Hence it is verynecessary to test the consistency of judgment matrix Whenthe consistency of judgmentmatrix is satisfied themaximumeigenvalue of the judgmentmatrix120582max should be equal to thenumber of indicators which are related to two consistencytest indices namely CI and CR
Consistency index (CI) which measures the divergenceof judgment matrix away from the consistency is defined asfollows
CI =120582max minus 119899
119899 minus 1 (1)
where 119899 represents the number of indicesThus the consistency ratio (CR) is defined as follows
CR =CIRI
(2)
RI is the random consistency index which is the averagevalue of eigenvalues obtained by calculating the judgmentmatrix for more than 500 times The value of RI is given inTable 9
If CR lt 01 the weight vector is acceptable otherwisethe modification of the pairwise judgment matrix is needed
As listed in the last row in Tables 3ndash8 respectivelyall the pairwise comparison judgment matrixes satisfy theconsistency test
445 Substep 5 Calculate the Index Weight The globalweight of each indicator can be determined by multiplying
the local weight of the indicator with theweight of upper layerindicator which locates in the parent node above it
The local and global weights of each risk indicator inindex layer and the weight of each indicator in criteria layerare calculated which are listed in Table 10
45 Step 5 Calculate the Fuzzy Relation Matrix Accordingto the statistical result of the questionnaire by using a certainmathematical method such as frequency-based method andweighted averagemethod the first-level fuzzy relationmatrixR can be calculated as follows
R = (119903119894119895)119899times119898

where 119903119894119895is the membership degree of the 119895th remark in
remark set V for the indicator 119894 119894 = 1 2 119899 119895 =
1 2 119898 119899 is the number of indices and 119898 is the numberof risk grades in remark set V Different rows in the fuzzyrelation matrix R reflect the different membership degrees ofevaluated object subject to fuzzy set of each grade consideringdifferent evaluation indices
The frequency-based method is used to establish thefuzzy relation matrix in this paper the principle of which isif the number of experts and engineers who judge the ldquohighriskrdquo ldquomoderate riskrdquo and ldquolow riskrdquo is119898

46 Step 6 Make Fuzzy Composition Synthesize the first-level fuzzy relation matrix R with the local weight 119882
119871 and
then the membership matrix 119861119894could be obtained which is
call the first-level fuzzy comprehensive evaluation matrix
119861119894= 119882119871o119877 = (119887

Due to the hierarchical structure of the evaluation indexsystem the second-level fuzzy relation matrix 119877
1015840 needs to becalculated

Then combined with the weight matrix 119882 the second-level fuzzy comprehensive evaluation matrix B can be calcu-lated as follows
B = 119882o1198771015840 = (1198871 1198872 119887

47 Step 7 Rate and Conclude the Grade Level Accordingto the maximum membership degree principle when 119887
1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object
belongs to the 1198940grade
In this paper since 1198872
= max 119887119894(1 le 119894 le 3) =
04990 it is shown that the risk grade of ldquoZhejiang-FuzhourdquoUHV power transmission construction project belongs toldquomoderaterdquo which means the occurrence probability of thisproject risk is medium and the risk occurrence will causegeneral loss So it is necessary for the project managers to

carry out some specific risk control measures to make theconstruction of this project run successfully
At the meantime valuing the evaluation result of indi-cators in criteria layer in centesimal form can help projectmanagers to analyze the project riskmore efficiently Supposethe comment set V = [V
1 V2 V3] = 90 50 10 and then
the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10
= 362830
1198803= 01073 times 90 + 05905 times 50 + 03022 times 10
= 422
1198804= 01128 times 90 + 04736 times 50 + 04136 times 10
= 379660
1198805= 01710 times 90 + 05133 times 50 + 03157 times 10
= 442085
(12)
The centesimal value (119880) of risk evaluation of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project canbe calculated as
119880 = 01385 times 90 + 04990 times 50 + 03603 times 10
= 410205
(13)
Figure 8 compares the centesimal value of each indicatorin criteria layer and we can see

(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway

444 Substep 4 Consistency Test The consistency of relativeimportance judgment on each indicator made by expertsand engineers is the key prerequisite for using the AHP todetermine the weights of risk indicators Hence it is verynecessary to test the consistency of judgment matrix Whenthe consistency of judgmentmatrix is satisfied themaximumeigenvalue of the judgmentmatrix120582max should be equal to thenumber of indicators which are related to two consistencytest indices namely CI and CR
Consistency index (CI) which measures the divergenceof judgment matrix away from the consistency is defined asfollows
CI =120582max minus 119899
119899 minus 1 (1)
where 119899 represents the number of indicesThus the consistency ratio (CR) is defined as follows
CR =CIRI
(2)
RI is the random consistency index which is the averagevalue of eigenvalues obtained by calculating the judgmentmatrix for more than 500 times The value of RI is given inTable 9
If CR lt 01 the weight vector is acceptable otherwisethe modification of the pairwise judgment matrix is needed
As listed in the last row in Tables 3ndash8 respectivelyall the pairwise comparison judgment matrixes satisfy theconsistency test
445 Substep 5 Calculate the Index Weight The globalweight of each indicator can be determined by multiplying
the local weight of the indicator with theweight of upper layerindicator which locates in the parent node above it
The local and global weights of each risk indicator inindex layer and the weight of each indicator in criteria layerare calculated which are listed in Table 10
45 Step 5 Calculate the Fuzzy Relation Matrix Accordingto the statistical result of the questionnaire by using a certainmathematical method such as frequency-based method andweighted averagemethod the first-level fuzzy relationmatrixR can be calculated as follows
R = (119903119894119895)119899times119898

Then combined with the weight matrix 119882 the second-level fuzzy comprehensive evaluation matrix B can be calcu-lated as follows

1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object

04990 it is shown that the risk grade of ldquoZhejiang-FuzhourdquoUHV power transmission construction project belongs toldquomoderaterdquo which means the occurrence probability of thisproject risk is medium and the risk occurrence will causegeneral loss So it is necessary for the project managers to

(2) Grid company should try to sign a contract withlocal government which strives to make the localgovernment be responsible for land requisition houserelocation and crop compensation Grid companycan also set up aworking group to coordinate with thelocal government The determination of land com-pensation standards not only abides by the relevantlaws and regulations but also takes the opinions oflocal masses into consideration
(3) The terrain and ecological resources along the projectline should be fully understood when selecting theoptimal route Having some experienced practition-ers on the team and considering the local customsare better for the route determination During theproject construction the water and soil loss as wellas deforestation should be reduced as far as possibleWhen the project is finished the vegetation should berestored timely
Mathematical Problems in Engineering 13
(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway
6 Conclusions
In this paper a hybrid evaluation model based on AHPand FCE method is implemented to evaluate the risk ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionprojectThis hybrid evaluationmodel takes full advantages ofAHP and FCEmethod After the risk evaluation index systemis built the AHP is used to determine the index weightand FCE method is used to evaluate the project risk Finallythe specific risk control recommendations are proposed Themain results of risk evaluation of ldquoZhejiang-Fuzhourdquo UHVpower transmission construction project are as follows
(1) The risk grade of ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project belongs to ldquomod-eraterdquo which indicates the occurrence probability ofproject risk is medium and the risk occurrence willcause general loss
(2) ldquoSociety riskrdquo has the highest level and the next isldquopolicy and law riskrdquo ldquotechnique riskrdquo ldquonatural envi-ronmental riskrdquo and ldquomanagement riskrdquo respectivelyldquosociety riskrdquo ldquopolicy and law riskrdquo and ldquotechnologyriskrdquo should be paid more attention in the risk man-agement and control for ldquoZhejiang-Fuzhourdquo UHVpower transmission construction project
(3) Risk control recommendations for main risk criteriawhich include society risk policy and law risk andtechnology risk are proposed
(4) This hybrid evaluation model is feasible and effectivewhich can effectively evaluate the risk of UHV powertransmission construction project

444 Substep 4 Consistency Test The consistency of relativeimportance judgment on each indicator made by expertsand engineers is the key prerequisite for using the AHP todetermine the weights of risk indicators Hence it is verynecessary to test the consistency of judgment matrix Whenthe consistency of judgmentmatrix is satisfied themaximumeigenvalue of the judgmentmatrix120582max should be equal to thenumber of indicators which are related to two consistencytest indices namely CI and CR
Consistency index (CI) which measures the divergenceof judgment matrix away from the consistency is defined asfollows
CI =120582max minus 119899
119899 minus 1 (1)
where 119899 represents the number of indicesThus the consistency ratio (CR) is defined as follows
CR =CIRI
(2)
RI is the random consistency index which is the averagevalue of eigenvalues obtained by calculating the judgmentmatrix for more than 500 times The value of RI is given inTable 9
If CR lt 01 the weight vector is acceptable otherwisethe modification of the pairwise judgment matrix is needed
As listed in the last row in Tables 3ndash8 respectivelyall the pairwise comparison judgment matrixes satisfy theconsistency test
445 Substep 5 Calculate the Index Weight The globalweight of each indicator can be determined by multiplying
the local weight of the indicator with theweight of upper layerindicator which locates in the parent node above it
The local and global weights of each risk indicator inindex layer and the weight of each indicator in criteria layerare calculated which are listed in Table 10
45 Step 5 Calculate the Fuzzy Relation Matrix Accordingto the statistical result of the questionnaire by using a certainmathematical method such as frequency-based method andweighted averagemethod the first-level fuzzy relationmatrixR can be calculated as follows
R = (119903119894119895)119899times119898

46 Step 6 Make Fuzzy Composition Synthesize the first-level fuzzy relation matrix R with the local weight 119882

Then combined with the weight matrix 119882 the second-level fuzzy comprehensive evaluation matrix B can be calcu-lated as follows
B = 119882o1198771015840 = (1198871 1198872 119887

47 Step 7 Rate and Conclude the Grade Level Accordingto the maximum membership degree principle when 119887
1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object
belongs to the 1198940grade
In this paper since 1198872
= max 119887119894(1 le 119894 le 3) =
04990 it is shown that the risk grade of ldquoZhejiang-FuzhourdquoUHV power transmission construction project belongs toldquomoderaterdquo which means the occurrence probability of thisproject risk is medium and the risk occurrence will causegeneral loss So it is necessary for the project managers to

carry out some specific risk control measures to make theconstruction of this project run successfully
At the meantime valuing the evaluation result of indi-cators in criteria layer in centesimal form can help projectmanagers to analyze the project riskmore efficiently Supposethe comment set V = [V
1 V2 V3] = 90 50 10 and then
the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10
= 362830
1198803= 01073 times 90 + 05905 times 50 + 03022 times 10
= 422
1198804= 01128 times 90 + 04736 times 50 + 04136 times 10
= 379660
1198805= 01710 times 90 + 05133 times 50 + 03157 times 10
= 442085
(12)
The centesimal value (119880) of risk evaluation of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project canbe calculated as
119880 = 01385 times 90 + 04990 times 50 + 03603 times 10
= 410205
(13)
Figure 8 compares the centesimal value of each indicatorin criteria layer and we can see

(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway

method The eigenvector of judgment matrix with the max-imum eigenvalue is the weight vector of risk index whichdenotes the relative importance of indicators in the same levelwith regard to the indicators in the upper layer The weightvector of risk index is the relative importance of indicators
with regard to the upper layer indicator which is also calledthe local weight
In this paper the weights of indictors in criteria layer andlocal weights of indicators in index layer are calculated whichare lists in Tables 3ndash8 respectively

444 Substep 4 Consistency Test The consistency of relativeimportance judgment on each indicator made by expertsand engineers is the key prerequisite for using the AHP todetermine the weights of risk indicators Hence it is verynecessary to test the consistency of judgment matrix Whenthe consistency of judgmentmatrix is satisfied themaximumeigenvalue of the judgmentmatrix120582max should be equal to thenumber of indicators which are related to two consistencytest indices namely CI and CR
Consistency index (CI) which measures the divergenceof judgment matrix away from the consistency is defined asfollows
CI =120582max minus 119899
119899 minus 1 (1)
where 119899 represents the number of indicesThus the consistency ratio (CR) is defined as follows
CR =CIRI
(2)
RI is the random consistency index which is the averagevalue of eigenvalues obtained by calculating the judgmentmatrix for more than 500 times The value of RI is given inTable 9
If CR lt 01 the weight vector is acceptable otherwisethe modification of the pairwise judgment matrix is needed
As listed in the last row in Tables 3ndash8 respectivelyall the pairwise comparison judgment matrixes satisfy theconsistency test
445 Substep 5 Calculate the Index Weight The globalweight of each indicator can be determined by multiplying
the local weight of the indicator with theweight of upper layerindicator which locates in the parent node above it
The local and global weights of each risk indicator inindex layer and the weight of each indicator in criteria layerare calculated which are listed in Table 10
45 Step 5 Calculate the Fuzzy Relation Matrix Accordingto the statistical result of the questionnaire by using a certainmathematical method such as frequency-based method andweighted averagemethod the first-level fuzzy relationmatrixR can be calculated as follows
R = (119903119894119895)119899times119898

where 119903119894119895is the membership degree of the 119895th remark in
remark set V for the indicator 119894 119894 = 1 2 119899 119895 =
1 2 119898 119899 is the number of indices and 119898 is the numberof risk grades in remark set V Different rows in the fuzzyrelation matrix R reflect the different membership degrees ofevaluated object subject to fuzzy set of each grade consideringdifferent evaluation indices
The frequency-based method is used to establish thefuzzy relation matrix in this paper the principle of which isif the number of experts and engineers who judge the ldquohighriskrdquo ldquomoderate riskrdquo and ldquolow riskrdquo is119898

Thus the first-level fuzzy relation matrix R can becalculated just as follows

46 Step 6 Make Fuzzy Composition Synthesize the first-level fuzzy relation matrix R with the local weight 119882
119871 and
then the membership matrix 119861119894could be obtained which is

Then combined with the weight matrix 119882 the second-level fuzzy comprehensive evaluation matrix B can be calcu-lated as follows
B = 119882o1198771015840 = (1198871 1198872 119887

47 Step 7 Rate and Conclude the Grade Level Accordingto the maximum membership degree principle when 119887
1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object
belongs to the 1198940grade
In this paper since 1198872

04990 it is shown that the risk grade of ldquoZhejiang-FuzhourdquoUHV power transmission construction project belongs toldquomoderaterdquo which means the occurrence probability of thisproject risk is medium and the risk occurrence will causegeneral loss So it is necessary for the project managers to

carry out some specific risk control measures to make theconstruction of this project run successfully
At the meantime valuing the evaluation result of indi-cators in criteria layer in centesimal form can help projectmanagers to analyze the project riskmore efficiently Supposethe comment set V = [V
1 V2 V3] = 90 50 10 and then
the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10
= 362830
1198803= 01073 times 90 + 05905 times 50 + 03022 times 10
= 422
1198804= 01128 times 90 + 04736 times 50 + 04136 times 10
= 379660
1198805= 01710 times 90 + 05133 times 50 + 03157 times 10
= 442085
(12)
The centesimal value (119880) of risk evaluation of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project canbe calculated as
119880 = 01385 times 90 + 04990 times 50 + 03603 times 10
= 410205
(13)
Figure 8 compares the centesimal value of each indicatorin criteria layer and we can see

(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway
6 Conclusions
In this paper a hybrid evaluation model based on AHPand FCE method is implemented to evaluate the risk ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionprojectThis hybrid evaluationmodel takes full advantages ofAHP and FCEmethod After the risk evaluation index systemis built the AHP is used to determine the index weightand FCE method is used to evaluate the project risk Finallythe specific risk control recommendations are proposed Themain results of risk evaluation of ldquoZhejiang-Fuzhourdquo UHVpower transmission construction project are as follows
(1) The risk grade of ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project belongs to ldquomod-eraterdquo which indicates the occurrence probability ofproject risk is medium and the risk occurrence willcause general loss
(2) ldquoSociety riskrdquo has the highest level and the next isldquopolicy and law riskrdquo ldquotechnique riskrdquo ldquonatural envi-ronmental riskrdquo and ldquomanagement riskrdquo respectivelyldquosociety riskrdquo ldquopolicy and law riskrdquo and ldquotechnologyriskrdquo should be paid more attention in the risk man-agement and control for ldquoZhejiang-Fuzhourdquo UHVpower transmission construction project
(3) Risk control recommendations for main risk criteriawhich include society risk policy and law risk andtechnology risk are proposed
(4) This hybrid evaluation model is feasible and effectivewhich can effectively evaluate the risk of UHV powertransmission construction project

444 Substep 4 Consistency Test The consistency of relativeimportance judgment on each indicator made by expertsand engineers is the key prerequisite for using the AHP todetermine the weights of risk indicators Hence it is verynecessary to test the consistency of judgment matrix Whenthe consistency of judgmentmatrix is satisfied themaximumeigenvalue of the judgmentmatrix120582max should be equal to thenumber of indicators which are related to two consistencytest indices namely CI and CR
Consistency index (CI) which measures the divergenceof judgment matrix away from the consistency is defined asfollows
CI =120582max minus 119899
119899 minus 1 (1)
where 119899 represents the number of indicesThus the consistency ratio (CR) is defined as follows
CR =CIRI
(2)
RI is the random consistency index which is the averagevalue of eigenvalues obtained by calculating the judgmentmatrix for more than 500 times The value of RI is given inTable 9
If CR lt 01 the weight vector is acceptable otherwisethe modification of the pairwise judgment matrix is needed
As listed in the last row in Tables 3ndash8 respectivelyall the pairwise comparison judgment matrixes satisfy theconsistency test
445 Substep 5 Calculate the Index Weight The globalweight of each indicator can be determined by multiplying
the local weight of the indicator with theweight of upper layerindicator which locates in the parent node above it
The local and global weights of each risk indicator inindex layer and the weight of each indicator in criteria layerare calculated which are listed in Table 10
45 Step 5 Calculate the Fuzzy Relation Matrix Accordingto the statistical result of the questionnaire by using a certainmathematical method such as frequency-based method andweighted averagemethod the first-level fuzzy relationmatrixR can be calculated as follows
R = (119903119894119895)119899times119898

1 2 119898 119899 is the number of indices and 119898 is the numberof risk grades in remark set V Different rows in the fuzzyrelation matrix R reflect the different membership degrees ofevaluated object subject to fuzzy set of each grade consideringdifferent evaluation indices
The frequency-based method is used to establish thefuzzy relation matrix in this paper the principle of which isif the number of experts and engineers who judge the ldquohighriskrdquo ldquomoderate riskrdquo and ldquolow riskrdquo is119898

Then combined with the weight matrix 119882 the second-level fuzzy comprehensive evaluation matrix B can be calcu-lated as follows
B = 119882o1198771015840 = (1198871 1198872 119887

47 Step 7 Rate and Conclude the Grade Level Accordingto the maximum membership degree principle when 119887
1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object
belongs to the 1198940grade
In this paper since 1198872
= max 119887119894(1 le 119894 le 3) =
04990 it is shown that the risk grade of ldquoZhejiang-FuzhourdquoUHV power transmission construction project belongs toldquomoderaterdquo which means the occurrence probability of thisproject risk is medium and the risk occurrence will causegeneral loss So it is necessary for the project managers to

the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10

(2) Grid company should try to sign a contract withlocal government which strives to make the localgovernment be responsible for land requisition houserelocation and crop compensation Grid companycan also set up aworking group to coordinate with thelocal government The determination of land com-pensation standards not only abides by the relevantlaws and regulations but also takes the opinions oflocal masses into consideration
(3) The terrain and ecological resources along the projectline should be fully understood when selecting theoptimal route Having some experienced practition-ers on the team and considering the local customsare better for the route determination During theproject construction the water and soil loss as wellas deforestation should be reduced as far as possibleWhen the project is finished the vegetation should berestored timely
Mathematical Problems in Engineering 13
(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway

Then combined with the weight matrix 119882 the second-level fuzzy comprehensive evaluation matrix B can be calcu-lated as follows
B = 119882o1198771015840 = (1198871 1198872 119887

47 Step 7 Rate and Conclude the Grade Level Accordingto the maximum membership degree principle when 119887
1198940=
max 119887119894(1 le 119894 le 119898) we can judge that the evaluated object

carry out some specific risk control measures to make theconstruction of this project run successfully
At the meantime valuing the evaluation result of indi-cators in criteria layer in centesimal form can help projectmanagers to analyze the project riskmore efficiently Supposethe comment set V = [V
1 V2 V3] = 90 50 10 and then
the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10
= 362830
1198803= 01073 times 90 + 05905 times 50 + 03022 times 10
= 422
1198804= 01128 times 90 + 04736 times 50 + 04136 times 10
= 379660
1198805= 01710 times 90 + 05133 times 50 + 03157 times 10
= 442085
(12)
The centesimal value (119880) of risk evaluation of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project canbe calculated as
119880 = 01385 times 90 + 04990 times 50 + 03603 times 10
= 410205
(13)
Figure 8 compares the centesimal value of each indicatorin criteria layer and we can see

(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway

carry out some specific risk control measures to make theconstruction of this project run successfully
At the meantime valuing the evaluation result of indi-cators in criteria layer in centesimal form can help projectmanagers to analyze the project riskmore efficiently Supposethe comment set V = [V
1 V2 V3] = 90 50 10 and then
the centesimal value of each indicator in criteria layer can becalculated as follows
1198801= 01690 times 90 + 04679 times 50 + 03631 times 10
= 422383
1198802= 01005 times 90 + 04585 times 50 + 04310 times 10
= 362830
1198803= 01073 times 90 + 05905 times 50 + 03022 times 10
= 422
1198804= 01128 times 90 + 04736 times 50 + 04136 times 10
= 379660
1198805= 01710 times 90 + 05133 times 50 + 03157 times 10
= 442085
(12)
The centesimal value (119880) of risk evaluation of ldquoZhejiang-Fuzhourdquo UHV power transmission construction project canbe calculated as
119880 = 01385 times 90 + 04990 times 50 + 03603 times 10
= 410205
(13)
Figure 8 compares the centesimal value of each indicatorin criteria layer and we can see
1198805≻ 1198801≻ 1198803≻ 119880 ≻ 119880

(2) Grid company should try to sign a contract withlocal government which strives to make the localgovernment be responsible for land requisition houserelocation and crop compensation Grid companycan also set up aworking group to coordinate with thelocal government The determination of land com-pensation standards not only abides by the relevantlaws and regulations but also takes the opinions oflocal masses into consideration
(3) The terrain and ecological resources along the projectline should be fully understood when selecting theoptimal route Having some experienced practition-ers on the team and considering the local customsare better for the route determination During theproject construction the water and soil loss as wellas deforestation should be reduced as far as possibleWhen the project is finished the vegetation should berestored timely

(4) Keep close touch with the local government andpublic security organization in order to strengthen thesecurity of project construction the ldquomass incidentsrdquosuch as petitions demagoguism and demonstrationshould be paid close attention and some relatedmeasures such as propaganda and negotiation shouldbe taken timely strengthen the project constructionmanagement and perform civilized construction andreduce the negative impacts on local residents to aminimum
52 Risk Control Recommendations for ldquoPolicy and Law Riskrdquo
(1) The project-related personnel especially the projectmanagers should carefully study the policies andlaws related to land management deforestation loanand environmental protection and the related legalcounsel should be engaged in order to reduce the legalrisk during the project construction
(2) Strengthen the research on the policies and guidancedocuments related to energy development and plan-ning
(3) Strengthen the communication with the governmentdepartment to improve the efficiency of project exam-ination and approval
(4) Because the size and weight of UHV equipment arebigger and heavier the traffic laws and regulationsshould be carefully studied to avoid the conflictrelated to UHV equipment transportation Trans-portation limitations should be taken into considera-tion when selecting the UHV equipment and surveyon the transport route is very necessary
53 Risk Control Recommendations for ldquoTechnology Riskrdquo
(1) Track the meteorological information timely andarrange the construction plan according to theweather condition some necessary measures shouldbe taken to protect the equipment from rainwatersuch as building the temporary drain and increasingthe pumping equipment
(2) The earth-rock excavation should keep a reasonableproportion based on the quantity calculation
(3) For waterway transport due to the constant changeof shipping lane the simulation navigation shouldbe performed six months in advance to ensure thetransportation safety
(4) Measure the earth resistivity and design the ground-ing grid establish special subjects to study the impactsof ground resistance on UHVGIS equipment and theoperation of control and protection system
(5) Design the crossing construction based on differ-ent crossing facilities to reduce the risk and diffi-culty when crossing the electricity lines the crossingscheme should be designed at the design stage and
take the terrain characteristic along the project lineinto consideration
(6) The material transport plan should take weather andtransportation environment into consideration opti-mize the use of different transportation facilities andmake the fullest use of crawler-transporter vehicleand cableway
6 Conclusions
In this paper a hybrid evaluation model based on AHPand FCE method is implemented to evaluate the risk ofldquoZhejiang-Fuzhourdquo UHV power transmission constructionprojectThis hybrid evaluationmodel takes full advantages ofAHP and FCEmethod After the risk evaluation index systemis built the AHP is used to determine the index weightand FCE method is used to evaluate the project risk Finallythe specific risk control recommendations are proposed Themain results of risk evaluation of ldquoZhejiang-Fuzhourdquo UHVpower transmission construction project are as follows
(1) The risk grade of ldquoZhejiang-Fuzhourdquo UHV powertransmission construction project belongs to ldquomod-eraterdquo which indicates the occurrence probability ofproject risk is medium and the risk occurrence willcause general loss
(2) ldquoSociety riskrdquo has the highest level and the next isldquopolicy and law riskrdquo ldquotechnique riskrdquo ldquonatural envi-ronmental riskrdquo and ldquomanagement riskrdquo respectivelyldquosociety riskrdquo ldquopolicy and law riskrdquo and ldquotechnologyriskrdquo should be paid more attention in the risk man-agement and control for ldquoZhejiang-Fuzhourdquo UHVpower transmission construction project
(3) Risk control recommendations for main risk criteriawhich include society risk policy and law risk andtechnology risk are proposed
(4) This hybrid evaluation model is feasible and effectivewhich can effectively evaluate the risk of UHV powertransmission construction project
